How do you simplify this?

timama [110]

Notice how the top is an addition of two cubes, namely x and 2.

You can rewrite the equation as:

$\frac{x^{3} + 2^{3}}{x + 2}$

Now, (a + b)³ can be simplified down to (a + b)(a² - ab + b²)
Following the same pattern, we get:

$\frac{(x + 2)(x^{2} - 2x + 4)}{x + 2}$
$= x^{2} - 2x + 4$

Mikayla bought 5 skirts at $x each. Three of the 5 skirts came with a matching top for an additional $9 each. Write and simplify

strojnjashka [21]

So Mikayla bought 5 shirts for $x dollars each
this part of the expression we can call 5x
then 3 of the shirts came with an additional $9 each. 9x3=27
so the expression is 5x+27
